1.2 Description of Process
Single Stage Mixing
Salty crude is mixed with dilution water upstream of a mixer valve. As the salty crude and dilution water pass through the mixing valve they are efficiently mixed by utilizing a pressure drop of 1 bar. The dilution water has a lower salt content than the produced water in the crude. The salt content of the produced water is now diluted by addition of the dilution water. The mixed fluid then enters the desalter.
Dilution Water Heating
The dilution water is heated to the minimum inlet temperature before it is mixed with the Salty Crude. This process can be done utilizing a heat exchanger or any other method that the client wishes to utilize.
Desalter/Dehydrator
The desalter consists of an electrostatic dehydrator. The inlet fluid is effectively distributed along the whole length of the vessel by the use of the inlet distribution manifold. It is specially designed to provide full length utilization with elimination of mal-distribution. Also, an open bottom design allows sediments to drop out under gravity to eliminate possible clogging of the distributors. The wet oil passes upwards and passes through the electrostatic grids. At this point an electrostatic field is applied to the wet oil, utilizing an AC-Plus (AC) field as described below.
Advanced Desalter
The horizontal electrostatic oil desalter is a sophisticated and efficient piece
of oil dehydration equipment and is common worldwide. With XYZ Process
Inc design enhancements our Advanced Desalter provides enhanced oil
dehydration capabilities.
Electrostatic Field
The water molecule consists of a central oxygen atom with negative valence,
and two hydrogen atoms with positive valance. This results in a molecule that is electronically polar.
Normally the arrangement of the water molecules in the liquid phase is random. However, if the liquid phase is put in a high voltage electronic field, the water molecules will become directional with the negative oxygen atom pointed towards the positive potential. The conventional electrostatic field is an alternating field, powered by a voltage step up transformer. The electrodes are suspended in the oil phase of the dehydrator by insulating hangers. The low voltage side can be supplied to the voltage desired. XYZ Process Inc transformers are supplied with 12/16/20/23/25 kV high voltage taps. Different
high voltage taps are required to allow different voltage gradients to be applied to oil to find the most optimum coalescing voltage.

AC-Plus Field - In an AC field the field changes polarity and gradient according to the AC wave. In the AC field with the reversing potential and varying gradient, the water molecules vibrate due to their variation in shape from round to oval and back to round. This effectively breaks any stabilizing film, and the kinetic energy enhances coalesce. There is generally no movement of the droplets except in-place vibration, and no charge is transferred to the droplets.
AC-Direct Field - In an AC/DC field the polarity remains constant. This allows the polar water molecule to become attracted and physically move towards the nearest electrode. As it touches the plate a transfer of electrons occurs causing the water droplet to become charged and move toward the opposite electrode.
This movement of a large number of water molecules, additionally attraction between two oppositely charged water molecules, causes a rapid increase in coalescence when compared to an AC field.
After the water has been coalesced into larger droplets, the water falls out of the oil to very high efficiencies leaving extremely only extremely small quantities of diluted produced water behind with the oil. The water is removed from the oil at the bottom of the vessel utilizing multiple water outlet points. As the water content of the oil leaving the desalter is extremely small and has been diluted by fresh water, the effective salt content left behind in the oil is very small.
The oil is removed effectively along the whole left of the vessel by an oil collector manifold. Again this eliminates the possibility of mal-distribution, provided effective & reliable oil dehydration & desalting capabilities.
